He received a degree in economics from the University of London, and was an editor and journalist in Israel before moving to New York in 1952.

His work has been criticized for flawed methodology, ignoring archaeological and historical evidence, and mistranslations of ancient texts as well as for incorrect astronomical and scientific claims. Sitchin's ideas have been resoundingly rejected by scientists, academics, historians (including Sumerologists, Orientalists and Assyriologists) and anthropologists who dismiss his work as pseudoscience and pseudohistory. Sitchin's books have sold millions of copies worldwide and have been translated into more than 25 languages.

He asserted that Sumerian mythology suggests that this hypothetical planet of Nibiru is in an elongated, 3,600-year-long elliptical orbit around the Sun. Sitchin attributed the creation of the ancient Sumerian culture to the Anunnaki, which he stated was a race of extraterrestrials from a planet beyond Neptune called Nibiru. Zecharia Sitchin (J– October 9, 2010) was an author of a number of books proposing an explanation for human origins involving ancient astronauts. The 12th Planet brings to life the Sumerian civilization, presenting millennia-old evidence of the existence of Nibiru, the home planet of the Anunnaki and of the landings of the Anunnaki on Earth every 3,600 years, and reveals a complete history of the solar system as told by these early visitors from another planet.London School of Economics, University of London

Travelers from the stars, they arrived eons ago, and planted the genetic seed that would ultimately blossom into a remarkable species. The product of thirty years of intensive research, The 12th Planet is the first book in Zecharia Sitchin's prophetic Earth Chronicles series-a revolutionary body of work that offers indisputable documentary proof of humanity's extraterrestrial forefathers. Over the years, startling evidence has been unearthed, challenging established notions of the origins of Earth and life on it and suggesting the existence of a superior race of beings who once inhabited our world.
